Reef to reef.
Papua New Guinea—WHOI biologist Simon Thorrold injected pregnant female clownfish with a nontoxic chemical tag in April on a reef off Kimbe Island. The tag is incorporated into the ear bones (otoliths) of fish embryos and remains there throughout the fish’s life. When the fish are caught, scientists can remove the otolith and detect the tag. The breakthrough technique reveals where fish were born and where they dispersed. Such knowledge is key for managing and protecting reef fisheries.
